rangement, relation and construction of parts, and modification can be made within the purview of the invention and within the scope of the claim, without departing from the spirit and import of the invention.

What I claim is A pipe vise including a flat base plate, a pair of standards projecting upwardly from said base plate in spaced relation and having their top edges at their forward parts provided with synclinally arranged serrations, said serrations forming the fixed jaw of the vise, a pivot pin extending between the rear upper ends of said standards, a bell crank lever pivoted at its angle on said pin and having a long horizontal handle arm and a short vertical arm, lugs projecting down- 7 wardly from said base and al-ined with the centers of said jaws, a lever pivoted at one end between said lugs and having an enlarged central portion provided with a vertical opening, a link connecting the free end of the lever and the end of the short arm of the bell crank lever, said base having an open ing alined above the opening in the second mentioned lever, said opening being disposed centrally between said standards, a. chain engaging hook on the opposite side of the base from the opening and likewise disposed be tween said standards, a chain having its links selectively engageable on said hook and provided on its end with a bar having a portion passing through the opening in the base plate and substantially fitting the same and having a. terminal threaded portion extending through the opening in the second mentioned lever, and an adjusting nut mounted on said threaded end and bearing against the underside of the secondmentioned lever.
